Abstract

A patterning method forms a pattern including a lyophilic region and a lyophobic region. The method includes treating the surface of an object by exposing an atmosphere containing at least one gas selected from the group consisting of hydrogen, deuterium, deuterated hydrogen, and tritium; partially exposing the treated surface to light to form an exposed region and an unexposed region; and applying a liquid onto one of the exposed region and the unexposed region.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to methods for producing electro-optic devices such as organic electroluminescence display devices and surface-conduction electron-emitting display devices, illuminants such as fluorescent phosphors, color filters, and thin film transistors, and a patterning method used in these methods.

[0003] 2. Description of the Related Art

[0004] Electro-optic devices include liquid crystal display devices, electroluminescent display devices, and field emission display devices (FEDs). These devices may optionally use color filters or color illuminants to form color images.

[0005] An organic electroluminescent display device includes light-emitting elements for producing red (R), green (G), and blue (B) emissions. These light-emitting elements are conventionally prepared by a liquid jet method, such as an on-demand ink jet method. Specifically, an organic material is jetted onto predetermined regions intended...
